STEAM-BOILER ATTACHMENT.

Specification of Letters Patent.

Patented June 18, 1918.

To all whom it may concern:

Be it known that I, ALEXANDER GoLLINon, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county of Bronx and State of New York, have invented a new and Improved Steam-Boiler Attachment, of which the following is a full, clear, and exact description.

The object of the invention 1s to provide "a new and improved attachment for stationary steam boilers such as are used for generating steam for heating and power purposes, and arranged to insure proper combustion of the coal or other fuel and to utilize the latter economically and to the fullest advantage.

In order to accomplish the desired result, use is made of a flue in the form of a gooseneck leading from the smoke box of the boiler, a drum in which terminates the said the attachment as applied to a steam boiler partly shown broken away;

Fig. 2 is an enlarged sectional plan new of the attachment on the line 2-2 of Fig. 1 looking in the direction of the arrows;

Fig. 3 is a sectional side elevation of a modified form of the attachment; and

Fig. 4 is a cross section of the same on the line 4-4 of Fig. 3.

The stationary steam boiler 10 provided with the attachment is of usual construction and is provided with a fire box 11 connected by tubes 12 with a combustion chamber 13 connected by tubes 14 with a smoke box 15 at the front end of the boiler. From the top of the smoke box 15 extends a flue 20 in the form of a gooseneck having its terminal 21 merging with the top of a drum 22, from the top of which extends the curved inlet end 23 of a chimney flue 24 connected with a chimney 25.

In the upper portion of the drum 22 are arranged deflecting and retarding plates 30 and 31 provided with perforations and curved in outward directions to restrict the throats or entrances 32, 33 of the ends 21 and 23 of the lines 20 and 21. The bottom of the drum 22 is provided with a self-closing and self-opening door 40, hinged at one end at 41 and pressed on by a sprin 42 to normally hold the door 40 in close position. The door 40 swings automatically into open position by the weight of accumulated cinders on the door to periodically discharge such cinders from the drum 22. In the inlet end 23 of the chimney flue 24 is arranged a damper 50 of usual construction and under the control of the operator.

hen the boiler is in use, the products of combustion arising from the burning fuel in the fire box 11 pass into the smoke box 15 from which the products of combustion pass into the flue 20 and are retarded and deflected by the deflecting plate 30 so that a retarding action is had on the products of combustion in the smoke box 12 to insure proper combustion therein. The products of combustion, passing through the narrow throat 32 and the perforations in the plate 30, pass into the drum 22 and from the latter, by way of the perforations of the plate 31 and the narrow throat 33, into the end 23 of the chimney flue 24 to eventually through the latter to the chimney 25. It will be noticed that the deflecting and retarding plate 30 retards and deflects the products of combustion passing from the flue 20 into the drum 22, and the perforate retarding and deflecting plate 31 retards the products of combustion in their passage from the drum 22 into the chimney flue 24."

By the retardin action described a proper combustion of the fuel is obtained thus 1nsuring an economical use of the coal or other fuel burned in the fire box 11. The lower edges of the deflectin and retarding lwtes 30 and 31 are prefera ly serrated, as p ainly indicated in Fig. 2, thus preventmg cinders from adhering and accumulating on the said plates 30 and 31.

The attachment shown and described can be readily applied to boilers as now generally used in buildings for the generation of steam for heating or power purposes without requiring any change in the boiler itself.

As illustrated in the modified form in Figs. 3 and 4, the end of the boiler flue 61 connects with a drum 62 from which leads the inlet end 63 of the chimney flue 6d.

drum 62 extend two sets of spaced perforate plates 70 and 71-curved in opposite directions to retard the products of combustion in their passage through the drum 62. It will also be noticed that the outermost plate 70 is provided with retracted throats 72 and 73 for the ends 60 and 63 of the fluesfil and M, the same as above described in ref erence to the plates 30 and 31.

The operation of the modified form shown in Figs, 3 end is practically the seine as above described in reference to the construction illustrated in Figs i and 2 so that inn their description of the same is not deemed necessary.

Having thus described my iiwentioi'i I claim as new and desire to secure by Letters Patent: k
